Otolithic functions in patients with residual dizziness after successful repositioning manoeuvres for unilateral posterior canal BPPV.

OBJECTIVE: To evaluate otolithic functions in patients with residual dizziness after successful canalith repositioning procedures (CRPs) for unilateral posterior canal benign paroxysmal positional vertigo (BPPV), and to investigate possible risk factors. METHODS: This case-control observational study included healthy controls and patients with residual dizziness after improvement following CRP for BPPV. All participants were subjected to full history taking, otoscopy, audiological basic evaluation, Dix-Hallpike test to search for posterior canal BPPV, residual dizziness screening, and vestibular evoked myogenic potential (VEMP) testing. Between-group differences were assessed and possible factors associated with residual dizziness were identified by univariate analysis. RESULTS: A total of 50 patients with residual dizziness (mean age, 56.53 ± 7.46 years [29 female: 21 male]) and 50 healthy controls (mean age, 58.13 ± 7.57 years [20 female: 30 male]) were included. A significant difference in VEMP latencies was found between the patient and control group (delayed in the patient group), with no significant between-group difference in amplitude in both ears. Aging, female sex, long duration of BPPV, number of CRPs, cervical VEMP and ocular VEMP abnormalities, and winter onset, were significantly associated with the risk of residual dizziness. CONCLUSIONS: Residual dizziness is a frequent sequel of BPPV that may relate to otolithic dysfunction. VEMP changes were revealed in the form of delayed latencies.

The importance of Epley maneuver in posterior canal benign paroxysmal positional vertigo.

OBJECTIVE: We investigated symptom scores and quality of life in unilateral posterior canal benign paroxysmal positional vertigo (BPPV) patients. PATIENTS AND METHODS: In this retrospective and multicentric study, 78 patients with unilateral posterior canal BPPV (47 right-sided and 31 left-sided) were included. All patients have performed the Standard Epley maneuver. Features of the nystagmus [nystagmus duration (second), latent period (second)] and features of the disease [side (right or left-sided), disease duration (years), and recurrence of disease (present or absent)] were noted. Before and 1 week after the Epley maneuver, all patients were evaluated using the Vertigo Symptom Scale (VSS), Vertigo Dizziness Imbalance Symptom Scale (VDI-SS), and Vertigo Dizziness Imbalance health-related quality of life scale (VDI-HQoL). RESULTS: Our results showed that VSSs of the right-sided group were significantly higher than those in the left-sided group before and 1 week after the maneuver (p<0.05). One week after the maneuver, VDI-HQoLs of the left-sided group were significantly higher than those in the right-sided group (p<0.05). In all right-sided and left-sided groups, at 1 week after the maneuver, VSSs were significantly lower, and VDI-SSs and VDI-HQoLs were significantly higher than those before the maneuver (p<0.05). As VSS values increased, VDI-SS and VDI-HQoL values decreased (p<0.05). In the left-sided group, VSS values decreased, and VDI-HQoL values increased. As disease duration increased, VSS values increased before the maneuver (p<0.05). In females, VSS values increased, and VDI-SS and VDI-HQoL values decreased before the maneuver (p<0.05). CONCLUSIONS: In posterior canal BPPV, the Epley maneuver effectively decreased VSS values and increased VDI-SS and VDI-HQoL values. In the left-sided BPPV group, there were lower VSS values and higher VDI-HQoL values that showed better quality of life of the patients. Older age and female gender are other factors related to lower quality of life with higher symptom scores.

[Discussion and analysis the value of supine median³ nystagmus in the diagnosis and treatment of HC-BPPV].

Objective:To explore the clinical value of supine median³ nystagmus in the accurate diagnosis of horizontal semicircular canal benign paroxysmal positional vertigo（HC-BPPV）. Methods:A total of 187 patients with HC-BPPV admitted to the First Affiliated Hospital of Xi'an Jiaotong University from June 2020 to March 2021 were selected. Among them 42 cases of Cupulolithiasis and 145 cases of Canalithiasis. The nystagmus parameters of patients left and right supine position and supine median³ position were recorded in detail by RART. According to the direction of supine median³ nystagmus, patients were divided into three groups: group A（nystagmus to weak side）, group B（nystagmus to strong side）, group C（negative nystagmus）. The canalith repositioning manoeuvres（CRM） was carried out by utility of an automatic vestibular function diagnosis and therapy system（SRM-IV）. The cure rate of CRM in three groups of HC-BPPV patients was compared, Multivariate logistic regression analysis was performed to analyze the influencing factors of CRM for HC-BPPV. Results:The cure rates of group A, group B and group C were 81.58%, 16.13% and 56.25%, respectively. The difference among the three groups was statistically significant. Then a pairwise comparison of group A, B and C, the difference was statistically significant（χ²A-B=40.294,P<0.001,χ²B-C=14.528, P<0.001,χ²A-C=11.606, P=0.001）; the results of multivariate logistic regression analysis showed that the direction of supine median³ nystagmus and BMI were the influencing factors of CRM for HC-BPPV. Conclusion:The direction, intensity and duration of supine median³ nystagmus play an important role in determining the responsibility semicircular canal of HC-BPPV.

Anxiety characteristics in benign paroxysmal positional vertigo: first vs. recurrent episodes.

PURPOSE: To assess the difference in state and trait anxiety levels in patients with Benign Paroxysmal Positional Vertigo (BPPV) at the first episode (FE) versus recurrent episodes (RE), before and after vestibular physiotherapy. A secondary objective was to assess the difference in the prevalence of underlying health conditions between FE and RE BPPV patients. METHODS: Fifty-five patients with BPPV, aged 40-70, were recruited. The diagnosis of BPPV was confirmed based on subjective complaints of vertigo and positive results from the Dix-Hallpike and Supine Roll tests. Twenty-four patients were in their FE, and 31 had RE. All patients completed the State-Trait Anxiety Inventory (STAI) questionnaire three times; before, immediately after, and a week after vestibular physiotherapy treatment. RESULTS: The RE group demonstrated higher trait anxiety than the FE group in all testing points: before treatment (median value of 38 versus 29, p-value = 0.02), immediately after treatment (median value of 36 versus 28, p-value < 0.01) and a week later (median value of 38 versus 28, p-value < 0.01). State anxiety decreased immediately after treatment in both groups, but at the second session, it was significantly higher in the RE than in the FE group (median value of 38 versus 28.5, p-value = 0.03). Hypothyroidism was significantly more frequent in the RE group (RE 16%, FE 0%, p-value = 0.04). CONCLUSIONS: Based on the current study's findings, we recommend assessing anxiety levels in patients with recurrent BPPV and consider referring them for appropriate treatment when necessary.

Procedural skills workshops for primary care physicians in Israel: a comprehensive analysis.

BACKGROUND: Some of the most common complaints addressed by primary care physicians (PCPs) require manual procedures, such as lacerations repair, abscesses drainage, ingrown toenails removal, dry needling for myofascial pain syndrome, and Epley maneuver for treating benign paroxysmal positional vertigo (BPPV). The aim of this study was to describe the procedural skills workshops program for PCPs implemented in Maccabi Healthcare Services and to investigate how many PCPs have participated and used the skills since the program's inception in 2017. METHODS: In this observational study, we followed all participants in courses from 2017 to 2021. We extracted all procedures performed during these years by PCPs who learned the skill in MHS. RESULTS: During the study period, 620 PCPs participated in workshops for dry needling, soft-tissue and joint injections, BPPV treatment, minor surgical procedures, and spirometry. Most procedures performed were dry needling (average annual number 3,537) and minor surgical procedures (average annual number 361). The average annual use per physician was highest for dry needling (annual average use per physician who used the learned skill was 50.9), followed by soft tissue and joint injections (16.8), minor surgical procedures (14.8), and BPPV treatment (7.5). CONCLUSION: procedural skills workshops may expand PCPs' therapeutic arsenal, thus empowering PCPs and providing more comprehensive care for patients. Some manual skills, such as dry needling, soft tissue injections, and the Epley maneuver, were more likely to be used by participants than other skills, such as spirometry and soft tissue injections.

Frailty of the.

Vestibular frailty and presbyvestibulopathy, including benign paroxysmal positional vertigo (BPPV), can cause dizziness among elderly patients. Vestibular frailty and presbyvestibulopathy may contribute to the onset of the vicious circle of falling-bone fracture-prolonged bedridden status-senile dementia. Treatment interventions for vestibular frailty and presbyvestibulopathy should be based on vestibular rehabilitation rather than vestibular implantation or regeneration. In acute BPPV, the otolith repositioning maneuver can be used to return otolithic debris to the utricle. At the chronic remission stage, there are nutritional guidelines for improving bone density in otolith organs and rehabilitation guidelines for activating otolith organs to prevent exfoliation. Moreover, sleeping in the head-up position can prevent free-floating debris from entering the semicircular canal. Throughout their old age, the psychiatric care/support is also indispensable to keep their initiative against vestibular frailty.

Hybrid maneuver for benign paroxysmal positional vertigo in individuals with limited neck mobility: Case series.

INTRODUCTION: Mobility limitation of the cervical spine compromises the adequate execution of the canalith repositioning maneuver (CRM) in cases of posterior semicircular canal benign paroxysmal positional vertigo (PSC-BPPV-GEO). Thus, novel therapeutic options are required for such individuals. OBJECTIVES: This study describes the effects of a change in the biomechanical position for the execution of the CRM on symptoms of dizziness and mobility limitation regarding flexion-extension of the cervical spine in older people with unilateral PSC-BPPV-GEO. METHODS: A quasi-experimental viability study was conducted with 15 older adults (11 women; mean age: 72.2 ± 8.1 years). Treatment consisted of a hybrid CRM. The participants were evaluated before and after the intervention using the modified Dix & Hallpike test, Dizziness Handicap Inventory (DHI) and a visual analog scale (VAS) for vertigo. RESULTS: The modified Dix & Hallpike test was negative in all cases after the execution of the hybrid CRM. A significant reduction was found for dizziness measured using the DHI (mean difference: -39.3 ± 9.4, p < 0.001) and VAS (mean difference: -2.9 ± 0.8, p = 0.04) after the intervention. CONCLUSION: The hybrid CRM proved executable and satisfactory for resolving symptoms of dizziness in older adults with PSC-BPPV. The present findings are promising and randomized controlled clinical trials should be conducted to evaluate the effectiveness of the hybrid CRM in this population.

Clinical characteristics of benign paroxysmal positional vertigo after traumatic brain injury.

INTRODUCTION: The aim of the present study was to evaluate the characteristics of brain injury and to assess the relationship between them and treatment outcomes in patients with traumatic benign paroxysmal positional vertigo (t-BPPV). MATERIALS AND METHODS: Sixty-three consecutive patients who were diagnosed with BPPV within 2 weeks after head trauma were included. RESULTS: Cerebral concussion, intracranial hemorrhages (ICH), skull fracture without ICH, and hemorrhagic contusion were observed in 68%, 24%, 5%, and 3% of t-BPPV patients, respectively. BPPV with single canal involvement was observed in 52 (83%) patients and that with multiple canal involvement was observed in 11 (17%) patients. The number of treatment sessions was not significantly different according to the cause of head trauma (p = 0.252), type of brain injury (p = 0.308) or location of head trauma (p = 0.287). The number of recurrences was not significantly different according to the cause of head trauma (p = 0.308), type of brain injury (p = 0.536) or location of head trauma (p = 0.138). CONCLUSION: The present study demonstrated that there were no significant differences in treatment sessions until resolution and the mean number of recurrences according to the type of brain injury.

Effects of Different Durations and Frequencies of Vestibular Rehabilitation in Patients With Residual Symptoms After Benign Paroxysmal Positional Vertigo Repositioning.

OBJECTIVES: This study aimed to explore the effects of different duration and daily frequency of vestibular rehabilitation (VR) in patients with residual symptoms after benign paroxysmal positional vertigo (BPPV) successful repositioning. METHOD: Patients with successful BPPV repositioning (n = 118) were divided into 3 groups according to VR duration and frequency: group A (n = 30; 15 minutes, 3 times/day), group B (n = 30; 30 minutes, 3 times/day), group C (n = 28; 15 minutes, 6 times/day), and control group D (n = 30; no VR). All patients completed the dizziness handicap inventory (DHI) and vestibular rehabilitation benefit questionnaire (VRBQ) at baseline and after 2 and 4 weeks. RESULTS: The emotional scores and the proportion of severe dizziness disability in the DHI scores were significant differences between VR groups A to C and control group D after 2 and 4 weeks (all P < .05). There were significant differences in total DHI and VRBQ scores among the VR groups A to C after 2 and 4 weeks (all P < .05). Interestingly, emotion scores were not significantly different in group A (P = .385), group B (P = .569), and group C (P = .340) between 2 and 4 weeks. Meanwhile at 2 weeks, the difference in motion-provoked dizziness score between group A and B was statistically significant (P = .02). CONCLUSIONS: A total VR duration over 4 weeks can reduce dizziness and improve VR benefits in routine therapy in patients with residual dizziness after successful BPPV repositioning. Emotional improvement can be observed after 2 weeks. VR may help to relieve motion-provoked dizziness earlier if patients are willing to consider increasing the duration to more than 15 minutes.

Bilateral simultaneous presentation of posterior canal benign paroxysmal positional vertigo.

OBJECTIVE: To outline the clinical picture of bilateral posterior canal benign paroxysmal positional vertigo. METHODS: A total of 573 patients with posterior canal benign paroxysmal positional vertigo were classified as having unilateral, or true or pseudo bilateral, posterior canal benign paroxysmal positional vertigo, and were treated with the Epley manoeuvre. Statistical significance was set at p < 0.05. RESULTS: Of the patients, 483 had unilateral and 90 (15.7 per cent) had bilateral presentation. Of the latter, 72 patients had pseudo bilateral posterior canal benign paroxysmal positional vertigo. Comparisons of site of involvement, male to female ratio and the incidence of associated problems in unilateral, and true and pseudo bilateral posterior canal benign paroxysmal positional vertigo did not reveal any statistically significant differences (p = 0.828, p = 0.200, p = 0.142). Comparisons of the number of manoeuvres required to provide symptom relief and the rate of recurrence were significant (p < 0.05). CONCLUSION: Identification of true and pseudo bilateral posterior canal benign paroxysmal positional vertigo is important given the differences in aetiology and treatment outcome. Treatment of patients with true bilateral posterior canal benign paroxysmal positional vertigo requires several therapeutic manoeuvre attempts, and patients should be warned about recurrence.

Posterior semicircular canal cupulolithiasis during acute pontomedullary demyelination.

Positional vertigo poses a diagnostic challenge in people with multiple sclerosis (MS). The characteristics of positional nystagmus and its response to repositioning manoeuvres are usually sufficient to diagnose benign paroxysmal positional vertigo (BPPV). However, certain BPPV variants respond poorly to repositioning manoeuvres and their nystagmus pattern can resemble that of central positional vertigo caused by infratentorial demyelination. This diagnostic difficulty is particularly challenging if positional vertigo occurs during an MS relapse. We describe a woman with MS who developed a sixth nerve palsy and gaze-evoked nystagmus, caused by demyelination near or within areas classically involved in central positional vertigo. However, she also had positional vertigo from coincident BPPV (and not central positional vertigo). This was initially a treatment resistant-posterior semicircular canal cupulolithiasis but it later progressed to a posterior semicircular canal canalolithiasis, with symptoms promptly resolving after a repositioning manoeuvre.

Clinical outcomes for various benign paroxysmal positional vertigo (BPPV) diagnoses in adolescents and young adults with recent concussions.

OBJECTIVE: Determine how positive BPPV findings in adolescents and young adults following concussion impacted the total number of treatments required and time until discharge. SETTING: Outpatient physical therapy clinic. PARTICIPANTS: 167 individuals who were diagnosed with concussion or brain injury. DESIGN: Retrospective chart review. MAIN MEASURES: Total number of treatments and days until discharge were compared for various BPPV diagnoses (anterior canal, posterior canal, horizontal canal, and combination) and for individuals with and without BPPV. RESULTS: Fifty-one out of 167 cases (30.54%) were diagnosed with BPPV. The total number of treatments provided was statistically different across BPPV diagnoses (P = .004). However, days until discharge were not statistically different between BPPV diagnoses (P = .28). There was no significant difference between time to discharge between those with BPPV (median = 21 days, range = 7-126) and those without (median = 28 days, range = 7-84 days; P = .23, r = 0.09). CONCLUSION: To optimize outcomes, including symptom resolution and return to sport and/or work, early identification of BPPV and subsequent intervention should be prioritized for individuals who have concussion symptoms that suggest vestibular dysfunction.

Risk Factors and a Nomogram Model for Residual Symptoms of Cured Benign Paroxysmal Positional Vertigo.

BACKGROUND: We aimed to analyze the independent risk factors that affect the treatment outcomes of residual symptoms of cured benign paroxysmal positional vertigoand to construct a nomogram model. METHODS: A total of 186 benign paroxysmal positional vertigo patients who were treated in our hospital from June 2019 to August 2021 were selected. According to whether there were residual symptoms, they were divided into a group with residual symptoms (n=82) and a group without residual symptoms (n = 104). The logistic regression model was used to analyze the independent risk factors affecting the treatment outcomes, and the results were incorporated into R software to establish a nomogram model for verification. RESULTS: The incidence rate of residual symptoms in the 186 patients was 44.09% (82/186). Logistic regression analysis showed that age, course of disease, number of maneuvers, anxiety state, diabetes mellitus, and hypertension were independent risk factors affecting the treatment outcomes of residual symptoms after cured benign paroxysmal positional vertigo. The area under the receiver operating characteristic curve of the nomogram model was 0.938. The calibration curve was fitted well (χ2 = 8.165, P = .417). CONCLUSION: The nomogram model constructed based on age, course of disease, number of maneuvers, anxiety state, diabetes mellitus, and hypertension had a high predictive value for the treatment outcomes of residual symptoms in benign paroxysmal positional vertigo patients.

Benign paroxysmal vertigo of childhood.

Benign paroxysmal vertigo of childhood (or recurrent vertigo of childhood) is the most common cause of vertigo in young children. It is considered a pediatric migraine variant or precursor disorder, and children with the condition have an increased likelihood of developing migraine later in life than the general population. Episodes are typically associated with room-spinning vertigo in conjunction with other migrainous symptoms (e.g. pallor, nausea, etc.), but it is rarely associated with headaches. Episodes typically only last for a few minutes and occur with a frequency of days to weeks without interictal symptoms or exam/test abnormalities. Treatment is rarely necessary, but migraine therapy may be beneficial in cases where episodes are particularly severe, frequent, and/or prolonged. An appreciation of the typical presentation and characteristics of this common condition is essential to any provider responsible for the care of children with migraine disorders and/or dizziness. This chapter will review the current literature on this condition, including its proposed pathophysiology, clinical presentation, and management. This chapter also includes a brief introduction to pediatric vestibular disorders, including relevant anatomy, physiology, embryology/development, history-taking, physical examination, testing, and a review of other common causes of pediatric dizziness/vertigo.

Epley manoeuvre's efficacy for benign paroxysmal positional vertigo (BPPV) in primary-care and subspecialty settings: a systematic review and meta-analysis.

BACKGROUND: Although previous studies have reported general inexperience with the Epley manoeuvre (EM) among general physicians, no report has evaluated the effect of EM on benign paroxysmal positional vertigo (BPPV) in primary care by using point estimates or certainty of evidence. We conducted this systematic review and meta-analysis and clarified the efficacy of EM for BPPV, regardless of primary-care and subspecialty settings. METHODS: Systematic review and meta-analysis of randomised sham-controlled trials of EM for the treatment of posterior canal BPPV in primary-care and subspecialty settings. A primary-care setting was defined as a practice setting by general practitioners, primary-care doctors, or family doctors. A systematic search was conducted in January 2022 across databases, including Cochrane Central Resister of Controlled Trial, MEDLINE, Embase, Cumulative Index of Nursing and Allied Health Literature, World Health Organization International Clinical Trials Registry Platform, and ClinicalTrials.gov. Primary outcomes were the disappearance of subjective symptoms (vertigo), negative findings (Dix-Hallpike test), and all adverse events. We evaluated the certainty of evidence using the Grading of Recommendations, Assessment, Development and Evaluation approach. RESULTS: Twenty-seven randomised controlled trials were identified. In primary-care settings, EM reduced the subjective symptoms [risk ratio (RR), 3.14; 95% confidence interval (CI), 1.96-5.02]; however, there was no applicable article for all adverse events. In the subspeciality setting, EM reduced the subjective symptoms (RR, 2.42; 95% CI, 1.64-3.56), resulting in an increase in negative findings (RR, 1.81; 95% CI, 1.40-2.34). The evidence exhibited uncertainty about the effect of EM on negative findings in primary-care settings and all adverse events in subspecialty settings. CONCLUSIONS: Regardless of primary-care and subspecialty settings, EM for BPPV was effective. This study has shown the significance of performing EM for BPPV in primary-care settings. EM for BPPV in a primary-care setting may aid in preventing referrals to higher tertiary care facilities and hospitalisation for follow-up. TRIAL REGISTRATION: The study was registered in protocols.io (PROTOCOL INTEGER ID: 51,464) on July 11, 2021.

Horizontal semicircular canal benign paroxysmal positional vertigo treated by acupuncture and moxibustion: A case report.

RATIONALE: Horizontal semicircular canal benign paroxysmal positional vertigo (HSC-BPPV) is a second common canal of Benign Paroxysmal Positional Vertigo (BPPV); its actual incidence may have been underestimated because of its complex pathogenesis. Although the canalith repositioning maneuver is the treatment of choice, it has a high recurrence rate, affecting some patients' lives and psychology. We submit a case report describing acupuncture and wheat grain moxibustion treatment for HSC-BPPV. PATIENT CONCERNS: A 70-year-old patient with HSC-BPPV had low acceptability of the otolith repositioning treatment strategy and reported intolerance during the procedure. He turned to acupuncture as a result of recurrent attacks of vertigo. DIAGNOSES: Horizontal semicircular canal benign paroxysmal positional vertigo. INTERVENTIONS: The intervention project was acupuncture followed by wheat grain moxibustion treatment, administered once every 2 days, 3 times a week. The whole treatment period lasted for 2 months. OUTCOMES: The patient's clinical symptoms of vertigo improved significantly after 8 weeks of acupuncture and wheat grain moxibustion treatment. The Dizziness Handicap Inventory (DHI) and Visual Vertigo Analogue Scale (VVAS) scores decreased, thus verifying that the severity of vertigo was reduced. LESSONS: This brief clinical report suggests that acupuncture therapy may be a complementary option for treating HSC-BPPV.

We should be screening for benign paroxysmal positional vertigo (BPPV) in all older adults at risk of falling: a commentary on the World Falls Guidelines.

Benign paroxysmal positional vertigo (BPPV) is amongst the commonest causes of dizziness and falls in older adults. Diagnosing and treating BPPV can reduce falls, and thereby reduce fall-related morbidity and mortality. Recent World Falls Guidelines recommend formal assessment for BPPV in older adults at risk of falling, but only if they report vertigo. However, this recommendation ignores the data that (i) many older adults with BPPV experience dizziness as vague unsteadiness (rather than vertigo), and (ii) others may experience no symptoms of dizziness at all. BPPV without vertigo is due to an impaired vestibular perception of self-motion, termed 'vestibular agnosia'. Vestibular agnosia is found in ageing, neurodegeneration and traumatic brain injury, and results in dramatically increased missed BPPV diagnoses. Patients with BPPV without vertigo are typically the most vulnerable for negative outcomes associated with this disorder. We thus recommend simplifying the World Falls Guidelines: all older adults (>60 years) with objective or subjective balance problems, irrespective of symptomatic complaint, should have positional testing to examine for BPPV.

[Study on the influence of Barbecure combined with Epley on residual dizziness of horizontal canal benign paroxysmal positional vertigo by SRM-vertigo diagnosis system].

Objective:To investigate the influence of Barbecure combined with Epley on residual dizziness of horizontal canal benign paroxysmal positional vertigo（HC-BPPV） by SRM-vertigo diagnosis system. Methods:A total of 406 patients diagnosed with HC-BPPV from Nov 2021 to Nov 2022 were enrolled by rapid axial roll test and Dix-Hallpike in the department of Otorhinolaryngology Head and Neck Surgery, the First Affiliated Hospital of Xi'an Jiaotong University. The patients were divided into two groups by hospital card numbers, in which the numbers that were odd were considered as group A, and the numbers that were even were considered as group B. The group A underwent two circles of Barbecure repositioning procedure by SRM-vertigo diagnosis system, while the group B underwent two circles Barbecure combined with Epley repositioning procedure by SRM-vertigo diagnosis system. The treatment was stopped on the next day when two groups of patients were cured, and those who were not cured will continue treatment with the same method. Results:The cure rate of group A was 83.41%, and the cure rate of group B was 80.51%, the difference between the two groups was not-statistically significant difference（P>0.05）. The rate of residual dizziness of group A was 23.30%, the rate of residual dizziness of group B was 11.46%, the difference between the two groups was statistically significant（P<0.05）. Conclusion:The Barbecure combined with Epley otoliths repositioning maneuver by SRM-vertigo diagnosis system can significantly reduce the rate of residual dizziness after the treatment of HC-BPPV, and improve the quality of life of patients.

Early treatment for benign paroxysmal positional vertigo secondary to sudden sensorineural hearing loss.

Sudden sensorineural hearing loss (SSNHL) accompanied by benign paroxysmal positional vertigo (BPPV) is relatively common in the clinic. There are unified standards for the treatment of primary BPPV with good reduction effect, while there are few studies on the treatment of BPPV secondary to SSNHL within 1 week of onset. The study was to investigate the treatment of BPPV secondary to SSNHL and compare its manual reduction with that of primary BPPV. We selected 90 patients with BPPV accompanied by SSNHL within a week of onset and 210 primary BPPV patients at Hebei Provincial Eye Hospital from June 2020 to December 2022. The former group was divided into the medicine group and manual reduction plus medicine group. The medicines used were extract of Ginkgo biloba leaves injection, betahistine hydrochloride injection and oral prednisone. We contrasted the efficacy respectively for posterior semicircular canal BPPV (psc-BPPV), horizontal semicircular canal BPPV (hsc-BPPV) and multiple semicircular canal BPPV (msc-BPPV). In addition, we compared the manual reduction effect for primary BPPV and manual reduction group, and the evaluation of efficacy are the intensity of nystagmus and the clinical symptoms. In the secondary BPPV group, there was no difference in efficacy between the medicine group and manual reduction group at the 7th-day after reduction for psc-BPPV, hsc-BPPV, and msc-BPPV (P > .05). The immediate effect of reduction was significantly different between the primary BPPV group and the group with SSNHL and BPPV for both psc-BPPV and hsc-BPPV (P < .05), and the effect of the primary BPPV group was better, but it was no difference for msc-BPPV (P > .05). For the treatment of BPPV accompanied by SSNHL within 1 week of onset, the additional reduction therapy showed no benefit, so we need to apply medication for SSNHL.

[Diagnosis and treatment of benign paroxysmal positional vertigo with manual and motorized chairs - Indication and value]. / Abklärung und Behandlung des benignen paroxysmalen Lagerungsschwindels mittels manueller und motorisierter Drehstühle.

Benign paroxysmal positional vertigo (BPPV) is the most frequent cause of episodic vertigo or dizziness. While this diagnosis can be made reliably in most cases by use of targeted history taking followed by provocation maneuvers on the examination couch and subsequent repositioning maneuver, these maneuvers may not be applicable in a subgroup of patients with pre-existing conditions such as musculoskeletal or neurologic disorders. At the same time, part of patients treated on the examination couch will not respond to the repositioning maneuvers. The use of a manual or motorized turntable thus extends both the diagnostic and therapeutic options in BPPV. Thus, it enables patients with disabilities that do not tolerate classic maneuvers on the examination couch access to the required diagnostic procedures and - if needed - provides targeted treatment as well. Furthermore, turntables extend both the diagnostic and the therapeutic spectrum, offering a broader range of repositioning maneuvers in unclear or treatment-refractory cases. In this narrative review potential indications are described and evidence for using turntables in the diagnosis and treatment of BPPV on the turntable is discussed.
